Lighting fixture



FIG. 1 is a bottom perspective view of a lighting fixture showing my new design;

FIG. 2 is a bottom plan view thereof;

FIG. 3 is a side elevational view thereof as seen from the direction of lines 3-3 in FIG. 1, the similarly rotated sides being identical thereto; and,

FIG. 4 is a side elevational view thereof as seen from the direction of lines 4-4 in FIG. 1, the similarly rotated sides being identical thereto.

The top of the lighting fixture is not part of the claimed design and therefore is not shown. The broken line showing of end caps on the arms of the lighting fixture are for illustrative purposes only; the broken lines form no part of the claimed design. 

The ornamental design for a lighting fixture, as shown and described.
